Answer:
so from looking at this we can see there is
0=5
1=5
2=3
3=2
4=4
5=1
6=2
7=2
8=1
9=1
now we have to add them up
5+6+16+5+12+14+8+9=75
and now we have to add up the total plots on the chart
5+5+3+2+4+1+2+2+1+1=26
now we divide
75 divided by 26=2.88461538462
so 2.9 is the mean
now we add up the number from least to greatest
0,0,0,0,0,1,1,1,1,1,2,2,2,4,4,4,4,5,6,6,7,7,8,9
so the medien is 4
Hope This Helps!!!
Step-by-step explanation:
Finding the median
The median is the number that is located in the middle of the set of numbers. First you count the number of X's, which is 26. This means that the median is in between number 13 and 14, which is 2 and 3 in this number set. Then you average the two numbers ([tex]\frac{2+3}{2}[/tex]) to get 2.5.
Finding the mean
The mean is the average of all of the numbers located in the set. First, you add up all of the numbers.
5(0) + 5(1) +3(2) + 2(3) +4(4) + 1(5) + 2(6) + 2(7) + 1(8) + 1(9) = 81
After, you divide by how many numbers there are in the set, which as we found earlier, is 26
[tex]\frac{81}{26}[/tex] = 3.12

Triangle MNP is dilated according to the rule DO,1.5 (x,y)Right arrow(1.5x, 1.5y) to create the image triangle M'N'P, which is not shown.
On a coordinate plane, triangle M N P has points (negative 4, 6), (2, 6), and (negative 1, 1).
What are the coordinates of the endpoints of segment M'N'?
M'(-6, 9) and N'(4, 9)
M'(-6, 9) and N'(3, 9)
M'(-2, 3) and N'(7, 9)
M'(-2, 3) and N'(1, 3)
Answers
Given:
The vertex of a triangle MNP are M(-4, 6), N(2, 6), and P(-1, 1).
The rule of dilation is:
[tex](x,y)\to (1.5x,1.5y)[/tex]
The image of triangle MNP after dilation is M'N'P'.
To find:
The coordinates of the endpoints of segment M'N'.
Solution:
The end points of MN are M(-4, 6) and N(2, 6).
The rule of dilation is:
[tex](x,y)\to (1.5x,1.5y)[/tex]
Using this rule, we get
[tex]M(-4,6)\to M'(1.5(-4),1.5(6))[/tex]
[tex]M(-4,6)\to M'(-6,9)[/tex]
And,
[tex]N(2,6)\to N'(1.5(2),1.5(6))[/tex]
[tex]N(2,6)\to N'(3,9)[/tex]
The endpoints of M'N' are M'(-6, 9) and N'(3, 9).
Therefore, the correct option is B.

Answer:
3) x = 55, y = 123, z = 123
4) x = 276°
Step-by-step explanation:
3)Angles P and Q are alternate interior angles, so are congruent.
P = Q
3x -42° = 2x +13°
x = 55° . . . . . . . . . . . add 42°-2x
Then Q = 2x +13 = 2(55°) +13° = 123°.
Angles Y, P, Q, and Z are all congruent, so all have the same measure.
Y = Z = 123°

4)If you draw a horizontal line parallel to AB and CD through point O, then small angle POQ is divided into parts that are congruent with angles APO and CQO. That is, small angle POQ = 48° +36° = 84°.
Large angle POQ is then 360° -84° = 276°

a rectangular field is 5x meters long and 2x m wide. if its perimeter is 140cm what is its area?
Answers
Answer:
1000 cm²
Step-by-step explanation:
perimeter = 2 * length + 2 * width
2 * 5x + 2 * 2x = 140
10x + 4x = 140
14x = 140
x = 10
Length: 5x = 5(10) = 50
Width: 2x = 2(10) = 20
area = length * width
area = 50 cm * 20 cm
area = 1000 cm²

Answer:
option D.
Step-by-step explanation:

let's take any point on the graph. let's say (2, 16)
and one point we know is (0, 0)
[tex]rate \: of \: change = \frac{16 - 0}{2 - 0} [/tex]
= 16($) / 2 (hrs)
= 8 $/ hrs
that is option D.
Answer:
$8/hour
Step-by-step explanation:
Hi there!
In this scenario, the independent variable is time and the dependent variable is the cost. The cost of renting the kayak depends on how much time passes. Knowing this, the answer should be formatted like _ dollars/hour, not _hours/dollar. We can rule the first two options out.
Now, looking at the graph, when 1 hour passes, the cost is $8. This occurs at point (1,8). And this is constant throughout, for example, when 2 hours pass, the cost is $16 (2,16).
Therefore, the rate of change shown in the graph is $8/hour.

The manufacturer is going to randomly select K parts from the shipment for inspection, and the shipment will be accepted if no defective parts are found in the sample. How large does K have to be to ensure that the probability that the manufacturer accepts an unacceptable shipment is less than 0.1? Hint: We recommend using R to plug in different values of K.

Given ABCD is a parallelogram Prove AB CD and BC DA. Assemble the proof by dragging tiles to the statements and reasons column

The proofing that ABCD is a parallelogram is done using parallelogram side theorem.
What is parallelogram side theorem?parallelogram side theorem simply means that the opposite sides of a parallelogram are equal and also parallel to each other.
As, ABCD is a parallelogram.
So, BAC and DCA are alternate interior angles.
Also, AB||CD and BC||DA.
then, BCA and DAC, are alternate interior angle.
Now In ABC and CDA
BAC= DCA (proved above)
BCA= DAC (proved above)
AC= AC (Common)
By ASA congruency criteria,
ΔABC≅ ΔCDA
Hence, AB= CD and BC= DA (cpctc)
